REFRIGERATING UNIT.

Application led September 14, 1923. Serial No. 662,741.

in an ice cream cabinet and connected to any suitable refrigeratingapparatus for maintaining the desired temperature within the cabinet.

Other objects have been to provide a refrigerating fcylinder which shallbe light in weight, and strong and durable in construction, andconvenient to use in existing cabinets.'

The above objects and advantages have been vaccomplished by the deviceshown in the accompanying drawings, of which:

Fig. 1 is a side elevation of my refrigerating cylinder, partly insection.

Fig. 2 is a plan, sectional view of the same, taken on line 2 2 of Fig.1.

Fig. 3 is a sectional elevation of my refrigerating unit.

Fig. 4 is a plan view, partly in section, of a :three-hole ice. creamcabinet equipped with my invention.

While my cylinder may be used in any existing ice cream cabinet, I havein the accompanying drawings shown a refrigerating unit embodying myinvention.

Referring to the drawings, 5 represents my rerigerating cylinder, whichis provided with an outer wall 6 and an inner wall 7. These walls arearranged finl interspaced relation, whereby a chamber 8 is provided..The chamber is provided with an inlet 9, preferably at' the bottom ofthe cylinder,

and with an outlet 10,Y preferably arranged on. the opposite side and atthe top of the cylinder. The cylinder does not have a top or bottom overits entire area, but it is y provided with a clear space through theentire' length ofthe same for the reception of the can 11 of ice cream.

In Figs. 3" and 4 of the drawings, I have 'shown my cylinder as appliedto an ice cream cabinet similar to the standard design. When .myCylinder is used in the cabinet,

land the outer Wall 12 of the. cabinet.

it is not necessary that the inner wall: of

opening, having a cover or stopper 14. A

bottom 15'is provided for the cabinet, and also a false bottom 16,between which is disposed cork or other suitable temperature insulatingmaterial. l

As shown in Fig. 3, my refrigerating cylinder rests upon the falsebottom 16, and extends to' a.po1nt near the top of the outer casing 12.Cork 18, or other temperature insulating material, ispacked in the spacebetween the outer wall 6 of the cylinder The top of the insulation 18 iscovered by means of a metallic plate 19 of suitable material. The plateis provided with a downwardly extending flanged portion 20, whichextends into the upper end of the refrigerating cylinder, whereby thecylinder and the packing are efficiently covered, thus making thecabinet sanitary. The inner wall 7 of my refrigerating cylinder is madeof such a size that the can 11 of ice cream may easily be placed withinthe cylinder. The can 11 is preferably kept separated from the falsebottom 16 by means of a number of cleats or wooden strips 21,

whereby the bottom of the can will be exposed to substantially the sametemperature as the exterior thereof.` In order to prevent atmosphericair from passing into the air space 24 and around the can 11, when thecover 14 is removed, I provide a gasket or closure 22, preferably roundin crosssection, which is placed around the upper end of the can 11 whenthe same is inserted within the cylinder. This gasket is held in placeby means of the usual bead 23 at the upper end of the can.

In Fig. 4, where I show a threehole ice cream cabinet, I show therefrigerating cylinders connected to each other and to a suitablerefrigerat-ing machine 25. The cylinders 5 are preferably arranged withtheir inlets and outlets at an angle of 45 with the side of the cabinet,whereby a more compact arrangement is obtained. A 0manifold 26,referably, connects the inlet o enings 9 o the cylinders, and a manifol27 connects the outlet o enings 10 of the cylinders. These manifo ds arepreferably of suitable piping, which is provided at spaced intervalsWith 45 T-fittings 28, which are conveniently connected to the inlet andout-f let openings preferably by means of union fittings 29.

Any suitable form of refrigerating machine may be used in connectionwith my refrigerating cylinder, and I have, therefore, shown at 25 aconventional form of machine.

By the use of my cylinder in an ice cream cabinet, it will be seen thatthecontents of the ice cream cabinet can be kept'at any desiredtemperature vithout the trouble and inconvenience entail by the dailyreplenishment of the ice a in the ordinary type of cabinet. The cabinetmay be kept more sanitary, and the refrigerating machme may be placed atany suitable or desired location, preferably in the basement of thebuilding,

2,0 Where the cabinet is located.

It will be clear from the foregoing, that no .coil is usedin connectionwith my c 1inder, but that the refrigerant itself is clrculated throughthe space 8 of the cylinder. It is obvious that, because of the shape ofthe cylinder, a very light, strong, and Huidtight device may be madewithout the da'nger of leakageA due to pressure exerted on the surfacesof the walls of the cylinder.

Having thus described my invention, what I claim is A refrigerating unitcomprising a cabinet having a false bottom, a refrigerating cylinderformed with open ends within` the cabinet and resting upon the falsebottom, insulation cabinet and the cylinder, and a metallic plateextending over the top of the insulation and the cylinder.

In witness 4whereof, I have hereunto signed my name.-
